Reducing end to end test execution time is key for software development life cycle that wish to implement continuous integration and delivery. Selenium WebDriver allows us to run e2e tests on web applications in different browsers. As it runs across many browsers and operating systems there are lots of possible capabilities to test. This workshop will help you to get started with the setup of dockerizing parallel execution of Selenium tests by cutting your test runtime up to 10 times. We’ll also look at how to run tests against a number of browsers and capabilities.
